Well hello all, just to give you a bit of info i'm looking to upgrade my stock 2017 Sonatas sound system. From what i have gathered i have a set of tweets and 2 sets of 6.5 and an 8" port for the subwoofer. Which from what it looks like is not installed. So with this I need to know kind of a way to head. I would like to keep the stock head unit and upgrade the speakers. I have no idea if i would have to go with an amp or not, but I'm looking for better sound not necessarily crazy bass or anything like that. Please tell me what you all think.
